ChatGPT Themes & Dark Mode — ThemeGPT

ThemeGPT is a Chrome extension that helps you personalize your ChatGPT experience. It allows users to change the look of the ChatGPT interface with different themes and also keeps track of your token usage. This means you can make ChatGPT look exactly how you want it and understand how much you are using the service.

Benefits

ThemeGPT puts your privacy first. All your chat information stays on your computer and is not sent to the developer. It also has a tool that counts how many tokens you use in real-time, showing you your input, output, and total usage. This counter can be seen directly on the ChatGPT page or in a small pop-up window. The extension is very easy to use right after installing it, with themes applying automatically. For those who want more, there are premium themes with cool animated effects like aurora lights or snowfall that run right in your browser.

Use Cases

This extension is great for anyone who uses ChatGPT regularly and wants a more comfortable or visually appealing experience. You can choose from many themes, including 7 free ones like ThemeGPT Dark, Dracula, and Solarized Dark. If you want something more special, there are 8 premium animated themes such as Aurora Borealis and Synth Wave. The token counter is useful for understanding your usage, especially if you are working with limits or costs associated with token counts.

Pricing (ONLY include if available)

Vibes (ONLY include if available)
